lawnmowers

Lawnmowers are devices designed to cut grass to a uniform height on lawns and similar areas. Most operate with one or more blades that rotate rapidly as the mower moves forward, severing grass blades cleanly.

Manual reel mowers are non-motorized and powered by pushing. They are quiet and emission-free but best suited to small, flat lawns.

Electric mowers come in corded and cordless forms. Corded models require a power outlet; cordless models use rechargeable batteries and offer greater mobility, with run times limited by battery capacity.

Gas-powered mowers use internal combustion engines, providing strong cutting power and independent range, but they are noisier, heavier, and require fuel and regular maintenance.

Robotic mowers are autonomous and programmable. They map the area, operate on a schedule, and return to a charging dock, often using boundary wires or sensors.

Common features include adjustable cutting height, deck width, and options for bagging, side discharge, or mulching. Some models are self-propelled.

Operation and safety: follow the manufacturer’s instructions, clear the area of stones and debris, wear eye and hearing protection, and keep hands away from the blade. For gas engines, disconnect the spark plug before servicing.

Maintenance involves keeping blades sharp, cleaning the deck, and inspecting belts and filters. Gas engines require oil changes and air-filter care; electric models need battery maintenance.

History and environment: the first lawn mower appeared in the 1830s, developed by Edwin Budding. Since then, powered, cordless, and robotic variants have become common. Electric and battery-powered mowers reduce direct emissions and noise, while gas models offer more power at the expense of fuel use and pollution.
